Some diseases are easily transmitted from animal to animal. Getting the dog checked out before taking it home will ensure any current pets are kept safe.
Another reason to take the puppy to a vet right away is to check for worms. Worms are common in dogs and puppies and are easily taken care of. Getting free dogs and puppies means the only costs you will incur are vet fees.
Finding dogs for free is something that needs some explaining, as taking care of an animal is never free. Being able to acquire a dog for free, however, is often quite a privilege, as some breeds' puppies can run above a thousand dollars for a single dog. The most obvious way to get dogs for free is through finding them. Be they stray dogs or abandoned puppies, some dogs with no obvious owner will let you interact with them. Regardless of whether it is someone's dog or not, it should not be approached if it growls or threatens you. If the dog is friendly, show it the back of your hand, palm towards the ground. If it responds well, check for a collar with a tag. If you can, there are a number of websites that will help owners locate their dogs for free.
